Carrier 50XL-A30 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrosting phase which assists to remove frost build-up that may accumulate. It relies on a sensor located somewhere by the condenser to verify when the defrost cycle should begin.
Important hints your defrost board is going out
- The defrost sequence never starts despite that there is a large amount frost on the external unit
- Your main control board could throw a specific error code if the defrost control board fails
- AC and heating system could stop working for the simple fact of the amount of frost on the outdoor unit
